Careful positioning of building elements, particularly windows in respect of prevailing wind directions and the movements of the sun will reduce the need for air conditioning and central heating, allowing the light in to the gallery space. Very often, the galleries and museums create an iconic structure, that attracts people into museums. A clever way of lighting up the exterior during the night time persuades the passers by to come back the next day.
"Closed" exhibition spaces with no day light give far greater control to the designer. Where there are no competing views of a gallery's surroundings, the visitor is forced to focus purely on the exhibition and its message. After roughly an hour the closed environment, especially where the light level is very low can become oppressive for visitors. The designers should therefore plan the rest stops. For example, Guinness Storehouse in Dublin is a mostly closed narrative journey that progress up the building and ends with a high-level panoramic view of the city.
Many contemporary designers of exhibition lighting learned their trade in the theatre, and the parallels between two disciplines are obvious. In both the light changes are applied to emphasise changes in the mood and tone. Daylight is very powerful compared to the most artificial light. Despite the movements of sun is predicted, one can never tell how the light will act during the day, for example, low clouds and rain will affect the lighting effects. Until artificial lighting was readily available, nearly all museums were lit through skylights above the exhibition hall, with light often filtering through central atrium to the floor below. Temporary shows are prone to be quickly made, and very often the designers do not even consider the natural lighting, so they usually prefer to block the light and create a completely artificial environment. For most of the time the light focus on display is brighter than the general background light, and it is called Accent light. Ambient light describes the light thrown into walls creating and overall brightness. Wall-wash enables the designers to light the whole wall relatively evenly. Wall-wash lights installed in sequence make it possible to create a wide continuos spread of light across long walls.

Visitors prefer ambient light, it is more comfortable then spotlight though less dramatic. There are 4 ways of lighting the 3D object. 1- From above with one lamp - very dramatic, allows to see the object properly only from one side. 2 - Side lighting, when the object is lit from two sides. 3 - Isometric, when there are 3 lamps. 4 - Underside, when the object is lit from below.
Feature lighting allows the designer to emphasise the shape and a 3 demential structure of the area, (the lights that are placed in the tops corner of the room) while accent light tends to break the 3 demential space by creating the light pools. LED lamps allow to see the transparent images and underline the silhouette of the object. Coloured filters, colour the space, they are extremely popular in exhibitions about science or virtual reality. A good example would be Wetland Museum in Hong Kong.

Projector lights are used to project signs, pattern and images into the flat surface of a floor. Edge lighting - the lamp, usually fluorescent, is placed to the edge of a translucent glass to create a glow around the display. The designer fills the box behind the surface with light, using soft diffuse lamps like fluorescent tubes. Boxes used for this are usually painted white to give maximum reflection. Parcan- light goes around a volume or a beam to which the letters or objects or some other kind of features attached.
